That big “E” on the wall of your family doctor’s office is looking blurry, and you’re off to your first-ever eye exam. Here’s a primer on what to expect when you get there. 



The tests before the tests

• First, you will be pre-tested, likely by a technician or an assistant. This consists of a series of tests, which will include a “puff test” to measure your internal eye pressure and detect glaucoma. None of this is painful or time-consuming, although the “puff test” (a quick puff of air against the eyeball) tends to startle people.

Next you’ll be introduced to the optometrist or ophthalmologist, who will take a thorough case history. This consists of your main concerns, if any, as well as your general health, family history, allergies and a list of any prescription drugs you may be taking.



All together now




Then the power of your eyes is measured to determine if you require eyeglasses and, if so, how strong. This will also include a measurement of how well your eyes work as a team.

Next, the doctor will use a slit lamp to look at the front of your eyes, including your eyelids, corneas and pupil reflexes.

Eyes wide open

Drops will then be administered to your eyes to dilate your pupils. It will take about 15 minutes for your pupils to fully dilate, so you will probably be asked to sit in a waiting area during this interval. Again, this procedure doesn’t hurt, but you’ll notice that your vision becomes more and more blurry as the drops do their work.

Pupil dilation allows the doctor to look inside your eyes for cataracts, macular degeneration and diabetic eye disease, among other things. Be sure to bring along a pair of sunglasses for your trip home, because dilated eyes are very sensitive to light for a few hours afterward.

Also, you will not be able to drive for several hours, until your pupils regain their normal size.

Further Testing

This is a typical exam and takes about 30 minutes in total. After the examination is finished, your doctor will review the results and talk with you about his or her recommendations.

Pediatric testing, laser surgery evaluations, contact lens consulting, glaucoma workups and other specialty testing require more time, and the doctor will advise you on this as necessary.

If you notice changes in your vision, see an eye care professional immediately, but even healthy individuals should have their eyes tested regularly.
